Seeing the man who suddenly appeared behind him, Lao Guo's face suddenly lit up with joy.
This person has a Chinese character face, piercing eyes, a high and shiny forehead, thick and fluffy black hair, and slightly protruding apple muscles. At first glance, he is a person who loves to laugh.
And it's very interesting.
At first glance, this man seemed to be in his forties, but upon closer inspection, he seemed to be in his early thirties, and his smile looked more like that of a young man in his twenties.
Saw this person appear.
Lao Guo quickly handed the box to Cai Shaohui, laughed and stepped forward to hug him hard:
"Guangda!"
After separation.
Lao Guo put his hands on both sides of the opponent's shoulders again, exerted a little force, and smiled and cursed:
"Well, Lu Guangda, when did you come back from Malan? I didn't hear any news about you when I left in the morning."
The middle-aged man named Lu Guangda grinned and showed a bright and innocent smile:
"I arrived not long after noon, probably two or three hours earlier than you. I just squinted in the dormitory for a while."
Said.
Lu Guangda's eyes fell on the suitcase in Cai Shaohui's hand, his expression moved slightly, and he guessed:
"Lao Guo, could this be..."
"Shh-"
Lao Guo quickly raised his index finger to his lips and made a silent gesture towards him.
Then he took Lu Guangda's hand and said to Li Jue and Peng Mengxiong beside him:
"Guangda, Lao Li, Lao Peng, there are many people here, let's go to the conference room to chat."
Li Jue and Lu Guangda looked at each other and nodded in unison.
Then Lao Guo looked at Cai Shaohui again, patted him on the shoulder, and said:
"Shaohui, you go back to the team to check on the situation. I'll be there later."
Cai Shaohui understood that they had important matters to discuss, so he naturally had no objection to it - although he was Lao Guo's partner, his position was just that of an ordinary researcher.
Although the employees who can enter Factory 221 have gone through strict political review, all of them are extremely reliable.
But whether it's Lu Guangda or Lao Guo, the things they deal with are top secrets among top secrets, so it won't hurt to be careful.
After the division of labor is completed.
Cai Shaohui said goodbye to several people.
Li Jue took Lao Guo, Peng Mengxiong and Lu Guangda to find a remote conference room and asked the security guards to be on guard outside.
After entering the house.
Peng——
Lao Guo put the box in his hand directly on the table and entered the six-digit password.
Click——
The combination lock popped open with a sound.
Then Lao Guo lifted up the box, revealing many foreign language journals inside, and said to Lu Guangda:
"I counted it again, and there were a total of 73 independently bound books, large and small."
"39 of them are printed documents, and the rest are handwritten contents. Guangda, come and take a look."
Hear this.
Lu Guangda quickly came to the password box and couldn't wait to read through it.
As he flipped through more and more journals, the expression on Lu Guangda's face became more and more excited.
Previously, the theoretical research group of the base compiled a batch of very critical data lists, the number of which was about 150.
According to Lu Guangda's idea, it would be good to get 10% of the money in the end.
After all, those comrades in the foreign affairs department don't know which issue of the journal contains these contents, so they can only quietly find out through their own relationships.
The result was unexpected.
This time, Lao Guo actually brought back more than 70 pieces of information, most of which were the content they had compiled before?!
This is really not easy...
Suddenly.
Lu Guangda's hand movements paused, then he let out a light sigh and his eyes fell on a handwritten English manuscript.
This manuscript only has three pieces of paper. The paper is very thin and can be easily clipped into one copy with a small clip.
Lu Guangda carefully held the manuscript in his hands and looked at the title above with shock:
"Steady-state subcritical state model..."
After a while.
Lu Guangda took a deep breath, suddenly turned his head, stared at Lao Guo, and asked:
"Lao Guo, where did this manuscript come from?"
"Steady-state subcritical state model... This is core-level data from the Los Alamos National Laboratory across the sea. It is absolutely, absolutely, absolutely impossible to spread nuclear theory secrets!"
When saying this.
Lu Guangda used three "absolutes" in a row, which shows his inner surprise.
Students who have done atomic bomb research should all know this.
In the development of nuclear weapons.
Theoretical design is the most important part.
In a sense.
It is more important than isolating uranium 235.
Each country's theoretical research on nuclear weapons is led by its own physics community.
For example, the theoretical design of the Manhattan Project across the sea was directed by Hans Bethe.
The Wooly Bear is hosted by Kurchatov.
John Bull hosted by Chadwick.
The person in charge of the theoretical design of the Rabbits is...
Lu Guangda.
When he first took office, he determined the main direction of the Rabbits' atomic bomb theoretical research:
Fluid mechanics, physical properties under high temperature and pressure, and neutron physics.
And in neutron physics?
Neutron transport is another absolutely core item.
Because the atomic bomb is described in theoretical terms, it can be summarized in the following sentence:
The so-called atomic bomb is to instantly change a nuclear device in a subcritical state into a highly supercritical state.
This is the relevant category of neutron transport.
To complete this step, one of the key technologies is...
Calculation method of unsteady neutron transport equation.
Of course.
The real core point of this equation lies in the calculation of high supercriticality in the motion state, which is an advanced version of the stationary subcritical state model that Lu Guangda had at this time.
This chapter is not over, please click on the next page to continue reading! But this does not mean that the stationary subcritical state model is not important.
Actually.
This model is considered core-level data for any country - because through this model, it is entirely possible to derive highly supercritical equations of motion states.
But now such a top-secret data model appeared in front of Lu Guangda...
How could this not surprise him?
Although there is not enough time for calculation.
But with Lu Guangda's superb physical literacy, after a few quick glances, he was at least 70% sure that this was a real model manuscript and not a bait deliberately released from across the sea.
And opposite him.
Looking at the handwritten manuscript in Lu Guangda's hand, Lao Guo's face instantly became extremely heavy.
"..."
I saw Lao Guo's chest rise and fall a few times, exhaled a heavy breath, and explained:
"Guangda, this is the information Changyou exchanged for."
"Nagatomo?"
Lu Guangda was slightly startled.
Subconsciously, a thin man appeared in his mind who was not tall, had some buck teeth, spoke with a strong Southern Fujian accent, and wore a British hat:
"What did he trade it for?"
Lao Guo glanced at him:
"Serve your life."
Use your life.
Two simple words.
However, Lu Guangda and Li Jue were instantly stunned.
Then Lao Guo sighed again, turned his attention to the manuscript in Lu Guangda's hand, and said:
"My friend did not return to China with us that year, but stayed at Los Alamos National Laboratory and served as Norris Bradbury's assistant."
"He has been providing all kinds of information for our research."
"After receiving secret letters from China last year, he began to accelerate the collection of various documents."
"I even took advantage of my position to obtain the relevant model of the stationary subcritical state - I don't know exactly how I obtained it. I am afraid that tens or hundreds of years later, this will remain an eternal mystery."
"Four months ago, he handed over the last batch of information to our comrades, and not long after he 'accidentally' fell to his death."
Lu Guangda heard this.
Subconsciously, I tightened the corners of the manuscript.
But before Lao Guo finished speaking, he only heard him say again:
"Two months ago, this box was sent to the Malay Peninsula, and my friend Brother Zu Ling was responsible for handing it over."
"It turned out that the news was leaked during the handover process. Fortunately, Brother Zu Ling brought another similar fake box in advance."
"He handed the real box to our comrades and left the scene with the fake box, trying to fool himself."
"Unexpectedly, the Malay British police officers did not even give them a chance to defend themselves during the pursuit. Later, I heard that Brother Zu Ling had 21 bullet holes in his body..."
Snapped--
Lao Guo just finished speaking.
Lu Guangda punched the table hard, his chest heaving violently.
Li Jue and Peng Mengxiong also had expressions as deep as water.
As one of the earliest batches of international students in China.
Many of Lao Guo and others...or it can be said that most of them left the country through channels such as "Gengqian".
But what they long for is not the blue sky and white sun, but the bright red five-pointed heart.
After the founding of New China.
Quite a number of Geng family members have made it clear that they are willing to return to China and make contributions.
1950.
Mr. Zhu Guangya took the lead in co-writing "An Open Letter to Students Studying in the United States" with 51 students studying in the United States, which set off a wave of overseas students returning to China.
Xinhuaxia has also cooperated in organizing many batches of international students. Over the past 20 years, more than a thousand international students have returned to China.
But again.
Considering that domestic non-applied physics research is lagging behind.
Therefore, some international students who were originally willing to return home immediately chose to stay across the sea after communicating with the country's senior officials.
over time.
Some of these international students have returned to China one after another more than ten or decades later and are contributing to the country.
Some did not fulfill the contract due to changes in their thinking, but stayed across the sea, or even chose to immigrate.
Others, like Mr. Zu Ling and Mr. Changyou, transported valuable information to the country through their own channels and sacrificed their lives for China's scientific research.
throughout the nuclear research enterprise.
More than 30 Chinese scientific researchers from a blood-stained foreign land have been made public, and the number that has not yet been declassified is probably not much less.
At the same time, it is even more regrettable.
Since a considerable number of these scientific researchers were overseas students with Geng Geng scholarships, they did not acquire Chinese nationality when they died.
Therefore, the rabbits are unable to even appeal.
At that time, the only person qualified to defend their rights was the island across the strait, but...
After a while.
Lu Guangda suddenly raised his head, looked at Lao Guo, and asked:
"Lao Guo, do you have a list of those comrades who died?"
Lao Guo nodded:
"Yes, but it is a simplified version compiled by myself. It only has the name and date of death, no photos and no resume."
Lu Guangda stretched out his hand towards him:
"show me."
Without much hesitation, Lao Guo reached into his inner pocket and took out a folded piece of paper from the pocket containing the pills.
Then he flattened the paper and handed it to Lu Guangda.
Lu Guangda took the paper with both hands and looked at it solemnly.
Then he sat back down, took out a pen and paper from his body, and started copying carefully.
Ma Zuling...
He Changyou...
Min Xuesi.....
A few minutes later.
Lu Guangda finished copying the list and handed the original copy back to Lao Guo.
Then he carefully folded the copied list in half and put it in the inner pocket of his chest.
Lu Guangda was calm throughout the whole process, but underneath this calmness, there was a flame burning.
.......
After a while.
Perhaps it was because the atmosphere in the conference room felt a bit dull.
Lao Guo coughed lightly and changed the topic:
"By the way, Guangda, what was your harvest from going to Malan Base this time?"
Lu Guangda tapped his index finger on the table a few times and shook his head:
"It's not ideal. The problem caused by the chain has been successfully solved, but the nuclide density during the chain transfer process has never been up to standard."
This chapter is not over, please click on the next page to continue reading! "So we must further efficiently concentrate radioactive materials, or consider slowing down neutrons to increase the probability of neutrons colliding with atomic nuclei and prolong the number of chain reactions."
"It's too hard to slow down neutrons."
After Lu Guangda finished speaking, Peng Mengxiong, who had not spoken much, quickly shook his head:
"This involves problems with existing materials. Unless the materials are quickly updated and iterated, it is impossible to achieve this step."
"But to further concentrate radioactive materials...it depends on whether the comrades in Jincheng can do it."
Say it.
Peng Mengxiong then looked at Li Jue who was standing aside.
Upon seeing this, Li Jue immediately raised his hand and expressed his stance:
"Jincheng, right? No problem. Leave the contact to me."
"Comrade Guangda, you'd better summarize the specific data or parameters that need to be met into a written report for me later. This will be more efficient."
Lu Guangda nodded:
"good."
Then he paused and asked Li Jue:
"Commander Li, I wonder how the construction of the base's detonation test site is going?"
I heard the words "detonation test site".
Lao Guo also showed a trace of concern on his face.
Mentioned before.
Among the current 221 factories, there are a total of 18 factory areas and 4 living areas.
The functions of each of these 18 factories are also different.
For example, Factory 17 is a warehouse for food and daily necessities, Factory 11 is a dangerous goods station, etc...
Among them, there are mainly five branches responsible for tasks related to nuclear weapons research, namely.
The first branch is responsible for warhead body processing, uranium component production, precision machining and radio system control.
The Second Branch is mainly responsible for the processing of explosives, simultaneous focus on experiments and the processing of pyrotechnic components and the assembly of nuclear weapons.
The third factory is a mechanical processing plant, responsible for sand foundry, forging, heat treatment, oxygen production, etc.
The Seventh Branch Factory is the experimental site for radiochemistry and neutron physics.
As for the No. 6 Branch Factory, it is...
Detonation test site.
This is a place responsible for detonation tests. It is large in scale and is still under construction even at this time.
The independent building modules under each branch factory have a special name called "work number".
Among them, the detonation test site plan has five job numbers, that is, five independent building modules.
"The explosion test site..."
Hearing this, Li Jue glanced at Lu Guangda and frowned slightly:
"To be honest, we also encountered some difficulties."
"Take the No. 2 observation room currently under construction at the detonation test site as an example. This observation room has very high requirements for the walls."
"So in addition to the material itself, there should be no rainfall or strong winds when the wall is poured - otherwise sand and gravel will be mixed into the wall."
"But currently our technology cannot accurately predict the climate. We can only ask the comrades of the sideline team to collect climate samples for analysis every day."
"Comrades have put in a lot of sweat, but in the end we still have difficulty controlling the weather conditions, which is very troublesome."
After hearing what Li Jue said.
Lu Guangda couldn't help but let out a "tsk" sound in embarrassment, clenched his hands into fists at his waist, and showed a gloomy look on his baby face.
Weather forecast...
This is indeed a big trouble.
The detonation test site is an important location used for explosion experiments in the mine. For the sake of personnel safety and experimental data collection, buildings such as observation rooms must strictly meet the standards.
But the problem is that the construction of the observation room involves the mysterious field of nature, and today's meteorological observation methods are obviously somewhat ineffective.
Currently, the factory-affiliated meteorological center of Factory 221 can only provide more accurate data for the day at 11 a.m. every day.
And to be honest at this time...
Ordinary people can tell what the weather will be like today by looking at the sky in the morning.
in this case.
In order to ensure that there will be no quality problems at the detonation test site.
The construction team can only wait for the meteorological center to provide accurate weather trends for the day...that is, after 11 noon, the construction team can start construction.
This way.
The period from early morning to morning at the construction site is wasted every day, a full ten hours.
If only someone could accurately predict the weather...
but....
is it possible?
.........
Note:
There was no update yesterday because I was on leave for surgery. Don’t worry too much. I haven’t received any review notification yet.
Due to timeliness reasons, the chapters cannot be synchronized with the facts, so you can join the book club group, and I will tell you anything in the group.
